Chii chinonzi lenzi yekutarisa yakasimbiswa?

Sezvinoratidzwa nezita racho,lenzi yekutarisa yakasimbiswaimhando yelenzi yekutora mifananidzo ine urefu hwakatarwa hwefocal, iyo isingagoni kugadziriswa uye inoenderana nelenzi ye zoom.

Kana tichienzanisa, malenzi ekutarisa akagadzirwa zvakanaka anowanzova neaperture yakakura uye optical quality yakakwira, zvichiita kuti akwanise kutora mifananidzo yemhando yepamusoro.

Musiyano uripo pakati pemalenzi ekutarisa akasimbiswa nemalenzi ekuona (zoom lenses)

Lenzi dzemagirazi dzakagadziriswa (fixed focus lens) nelenzi dzezoom (zoom lens) imhando mbiri dzemagirazi emakamera, uye musiyano mukuru uri pakuti urefu hwemagirazi emakamera hunogona kugadziriswa here. Ane zvakanakira zvawo kana akashandiswa mumamiriro akasiyana ekushandisa.

Semuenzaniso, lenzi yekutarisa yakagadzika yakakodzera kushandiswa mumamiriro ezvinhu ane chiedza chakakwana, kutsvaga mifananidzo yemhando yepamusoro, uye dingindira rekupfura rakagadzikana, nepo lenzi yekutarisa yakagadzika yakakodzera zviitiko zvinoda zoom inochinjika, senge kutora mifananidzo yemitambo.

Lenzi yekutarisa yakasimbiswa

Kureba kwefocal

Hurefu hwefocal lens ye fixed focus hwakagadzika, senge 50mm, 85mm, nezvimwewo, uye hahugone kugadziriswa. Lens ye zoom inogona kugadzirisa focal length nekutenderera kana kusunda nekudhonza lens barrel, zvichibvumira kusarudzwa kunochinjika pakati pe wide-angle ne telephoto.

Omashandiro emaziso

Kazhinji, alenzi yekutarisa yakasimbiswaine mhando ye optical iri nani pane zoom lens nekuti dhizaini yayo iri nyore uye haidi kutariswa kwekufamba kwe lens kana maumbirwo akaomarara e optical. Kana tichienzanisa, ma lens akasimba anowanzova ne aperture yakakwira (ine F-value diki), iyo inogona kupa mhando yemufananidzo iri nani, bandwidth yakawanda yechiedza, uye mhedzisiro iri nani yekusajeka kwemashure.

Asi ikozvino nekuvandudzwa kwetekinoroji, mamwe ma lenzi emhando yepamusoro anogonawo kusvika padanho rema lenzi akasimba kana tichitarisa mashandiro e optical.

Huremu uye vhoriyamu

Maumbirwo e lenzi yekutarisa yakapfava ari nyore, kazhinji kacho idiki uye yakareruka. Maumbirwo e lenzi yekutarisa yakaomesesa, ine ma lenzi akawanda, saka inowanzova yakakura uye inorema, izvo zvingasava nyore kuti vafotori vashandise.

Nzira yekupfura

Lenzi yekutarisa yakagadziriswas dzakakodzera kutora mifananidzo yezviitiko kana vanhu vakasiyana, sezvo kureba kwefocal hakugone kugadziriswa, uye malenzi akakodzera anofanira kusarudzwa zvichienderana nedaro rekupfura.

Lenzi ye zoom inochinjika zvishoma uye inogona kugadzirisa urefu hwefocal zvichienderana nezvinodiwa pakupfura pasina kuchinja nzvimbo yekupfura. Yakakodzera zviitiko zvinoda shanduko dzinochinjika pakupfura daro uye kona.
